lol sorry i just changed it in my post! for 22 degree approx what i meant to say was cosθ=1-\frac{θ^{2}}{2}
the information i really need is how the heck they did the taylor series expansion with that derivative. i have my old math book and i can see how they got the taylor series for sine...
Hey guys, I am looking for a textbook that I can cite as a source for a project, for which I am doing the math on.
I know that for a 22° approximation sinθ=θ and cosθ=1-\frac{θ^{2}}{2}
but for a 5° approximation sinθ=θ but now cosθ=1
and that's all fine and dandy, but I am looking...
about permeability.
yes anytime a permeable material is placed in a B field it will contain and concentrate the flux through it, because it does provide a path of lower reluctance. However the material in question can only contain a finite amount of flux. magnetic materials have two important...
I believe you meant period of oscillation when you were talking about nanoseconds and pico seconds. if the T (period) is >= 1 ns then we have GHZ frequencies, and if T>= 1ps then we have THZ frequencies.
an electromagnetic is simply an inductor. for frequencies that high, unless your...
Well this is true, however since I am an undergraduate (just a youngin) my post is geared towards curious undergraduates who would want to do more than just bury themselves in the taylor mechanics book or the griffiths E&M text.
and i do know that for particle physics, there is only so much you...
I just thought Id post some of my thoughts on what I feel is needed for undergrad physics majors who are interested in the more practical side of what we are learning in our highly idealized and theoretical coursework. I also would like to point out what tools I think are necessary for people...
the Arfken and Weber Mathematical Methods for Physicists should be rigorous enough for you - its the grad level text.
Or you could try a book titled "Advanced Engineering Mathematics" physics majors and engineers often take upper division math classes from a book with this such name. however i...
